Large Diameter Steel Pipe Painting Heat Treatment EquipmentThe notion of steel pipe painting is that steel pipe is preheated to required temperature and then the pipe wall is coated with a plastic powder. And the powder is melted and subsequently attached to the wall. Solid protective film can be formed after its cooling processing. The corrosion and wear resistance of steel pipe can also be well improved.First of all, preparation work of steel pipe is the preheat processing. The pipe wall surfaces that are to be coated are sandblasted so that there is no rust, no oil and no dust.Steel pipe painting processing:1.Steel pipe that is sandblasted is required to remove from sandblasting machine and is put on the material storage platform.2."Steel conveyor idlers" makes the steel transferred to "Preheat oven" entrance, "asked roller conveyor pipe" Stop. The pipe from the "steel roller conveyor tray" on hold, sliding the first tip of the steel ramp by scrolling to the "warm-up conveyor chain," after the pipe is in the place, "warm conveyor chain," a rotating station.3.Steel pipe that is heated to the preheated temperature should be taken from "taking the machine" and transferred to spray painting station.4."Taking the machine" under the action of cylinder raises a point of view and holds the preheated steel pipe and spray finish at the same time. After it is separately from the "warm conveyor chain" and "spraying rotating roll holder", the "take the chain tube" is rolling. After the pipe was transferred in place, the cylinder returns.5."Curing conveyor chain" is rotated and steel pipe will be transferred to "curing oven" to be cured.6."Gun walking" goes forward, the gun is inserted into the pipe. When the "gun" is walking to the other end of the pipe, then stops. Next is that "gun" backs, "to the powder" and "dusting pump" work. When the "gun" exits steel, "gun", "powder machine" and "dusting pump" stop work.Advantages: comprehensive painting and high efficiency.
